Build Notes

Endministrator — endgame dps

Rank #3

The endgame Crush DPS build centers on Grand Vision and Swordmancer gear to amplify Endministrator's Originium Crystal synergy. By applying Crush and consuming crystals, he gains massive Physical DMG bonuses and triggers the set's extra hit. This build is ideal for mono-Physical teams where he can consistently stack Vulnerability and deliver high burst damage.

Grand Vision is chosen because its Infliction effect grants +100.8% Physical DMG after applying Originium Crystals or Solidification, directly boosting Endministrator's Crush and Ultimate.

Swordmancer gear set increases Stagger Efficiency and deals bonus Physical DMG after each Physical Status, syncing with his Crush application.

Aethertech Gloves provide Arts Intensity, which improves Crush damage scaling.

Stat priority focuses on Agility (main attribute), Strength (secondary), Physical DMG Bonus, and Arts Intensity to balance raw damage and Crush effectiveness.

This build maximizes Endministrator's Crush damage and overall burst output.
Grand Vision's Infliction buff triggers off Originium Crystals, providing a massive Physical DMG boost.
Aethertech Gloves as off-piece adds extra Arts Intensity for Crush damage.
Swordmancer set bonus deals additional Physical DMG after applying a Physical Status, perfect for his rotation.

Endministrator — early game dps

Best in Slot

The early game build uses free and craftable gear to provide a solid foundation for Endministrator's Physical DPS role. Sundering Steel and Roving MSGR set emphasize Agility and Physical DMG, allowing him to deal respectable damage while learning his rotation. It's a reliable stepping stone toward the endgame build.

Sundering Steel is the best early weapon because it boosts Agility and Physical DMG, and its Combative effect increases ATK when dealing Physical Status (Crush).

Roving MSGR set directly boosts Agility and Physical DMG, matching Endministrator's primary and secondary stats.

This setup is cost-effective and strong enough to carry through midgame until endgame gear is available.

Early game build uses easily crafted Roving MSGR gear from Ferrium materials.
Sundering Steel is a free weapon from Operational Manual, providing Agility and Physical DMG.
Set bonus gives extra Physical DMG when HP is above 80%, easy to maintain in early content.

Chen Qianyu — endgame sub dps

Rank #2

This endgame build maximizes Chen Qianyu’s role as a Vulnerability sub‑DPS by concentrating on Ultimate and Combo Skill damage. Rapid Ascent, supported by the Swordmancer set, ensures frequent, hard‑hitting bursts while also boosting Stagger application. Agility and Strength are the primary stats to enhance Physical damage and skill scaling. Alternatives like Sundering Steel or Aspirant provide similar benefits for players who lack the best‑in‑slot weapon.

Rapid Ascent’s Twilight essence grants huge Physical DMG to battle skills and ultimates, especially against Staggered enemies, and its Critical Rate boost increases her damage consistency.

Swordmancer’s set effect triggers a 250% ATK Physical hit after applying a Physical status, which counts as Stagger application and amplifies her follow‑up damage.

Sundering Steel and Aspirant are excellent budget picks: Sundering Steel ramps ATK on Physical status, while Aspirant boosts Ultimate after applying Lift.

The mixed gear still activates Swordmancer’s 2‑piece bonus (Stagger Efficiency) and uses high‑stat pieces from Bonekrusha for extra Combo Skill damage.

Rapid Ascent is the best weapon because it boosts Ultimate damage and Critical Rate, synergizing with her burst‑focused playstyle.
The Swordmancer set provides Stagger Efficiency and an extra Physical hit after applying a status, which aligns perfectly with her kit.
Bonekrusha armor piece adds Combo Skill DMG and valuable stats, but the 4‑piece Swordmancer bonus isn’t required; mixing is fine.

Chen Qianyu — early game dps

Best in Slot

This early game build equips Chen Qianyu with Sundering Steel and the Roving MSGR set to capitalize on her Physical damage and Agility scaling. It is easy to assemble and provides a solid foundation for clearing early content. The focus is on maximizing ATK and Physical DMG through simple, reliable bonuses. Players should upgrade to the endgame build as they obtain better weapons and gear.

Sundering Steel’s Combative essence increases ATK by 14% and an additional 21% for 20s after inflicting a Physical status, stacking up to twice – easy to maintain with her skills.

Roving MSGR’s 2‑piece bonus (+50 Agility) and conditional Physical DMG +20% (above 80% HP) synergize with Chen Qianyu’s needs, as she is not a front‑line tank.

The gear pieces provide substats like Agility and Physical DMG, which directly improve her damage and skill scaling.

No alternatives are listed because this build is meant for early game before better options become available.

Sundering Steel is a strong early weapon because its ATK buff triggers easily from Physical status effects, which Chen Qianyu applies often.
The Roving MSGR set gives a flat Agility bonus and extra Physical damage when HP is high, making it very effective for early progression.
This build focuses on Agility to boost her primary attribute and improve overall damage output.

Pogranichnik — early game support

Rank #2

This early game build leverages accessible gear to support Pogranichnik's role as an SP battery. The Mordvolt Resistant set increases his Will stat, enhancing skill effectiveness, while Thermite Cutter provides a team ATK boost. Suitable for players progressing through the early stages without high-end gear.

Thermite Cutter is prioritized for its Will increase and team ATK buff, even at early game.

Mordvolt Resistant set improves Pogranichnik's primary attribute and offers survival utility.

Sundering Steel is an alternative if Thermite Cutter is unavailable, focusing on personal damage.

Mordvolt Resistant set boosts Will and provides healing bonus when HP is low.
Thermite Cutter is obtainable from the New Horizons banner, making it a strong F2P option.

Rossi — endgame sub dps

Rank #3

This endgame build focuses on stacking critical rate via the MI Security set and Lupine Scarlet weapon to capitalize on Rossi's innate crit damage buffs. The combination significantly boosts her personal damage and debuff uptime, making her a powerful sub-DPS in any team.

Lupine Scarlet is the best weapon because it increases Heat and Physical damage while providing crucial crit rate.

Glorious Memory is a strong alternative from the battle pass, boosting crit rate and Ultimate damage.

Sundering Steel and Wave Tide are lower-rarity options but lack crit rate, resulting in a significant damage gap.

MI Security set with Redeemer Gloves off-piece maximizes crit rate and Ultimate gain for smoother rotations.

Prioritize critical rate to fully utilize Rossi's critical damage buffs from Combo Skill and Ultimate.
The MI Security set's stacking ATK bonus and additional crit rate at max stacks greatly enhance overall DPS.

Rossi — early game sub dps

Best in Slot

This early game build maximizes Rossi's Combo Skill damage using the Aburrey's Legacy set and Sundering Steel weapon. It provides a strong foundation for her damage output while keeping stat investment simple.

Sundering Steel is the best early weapon as it increases Combo Skill damage and Physical DMG while boosting Agility.

Aburrey's Legacy set provides a substantial Skill DMG bonus and additional ATK after using any skill.

Roving MSGR Fists T1 is used as an off-piece for early availability.

Focus on increasing Agility to improve Rossi's damage output.
Aburrey's Legacy boosts Combo Skill damage significantly, which is Rossi's main damage tool early on.
